Abstract

Auralization is a powerful and cost-effective tool for communicating the impact of transportation noise sources on building occupants, and aiding the project team in making well-informed design decisions. An appropriately calibrated listening demonstration gives the owner, architect, and consultants the opportunity to directly experience annoyance, disturbance, and difficulty (or ease) of communication with others. This presentation will review lessons learned from practice to achieve an immersive and realistic listening experience, including suitable loudspeakers, recordings, receptor positions, transmission loss data, simulation and audio reproduction of moving sound sources. It will also cover important limitations of auralization in the context of transportation noise sources, including the difficulty of low frequency source characterization and transmission loss prediction, and the relevance of feelable vibration. Recent case studies of aircraft, rail, and automobile noise will be used to highlight the unique role of auralization in the design process of residential and commercial buildings.
